import CoreLocation
let locationManager = CLLocationManager()

override func viewDidLoad() {
       //先delegate才不会crash
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
        locationManager.requestLocation()
}

//MARK: - LocationManagerDelegate
extension WeatherViewController: CLLocationManagerDelegate{
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.last{
            let lat = location.coordinate.latitude
            let lon = location.coordinate.longitude
            weatherManager.fetchWeather(latitude:lat, longtitude:lon)
        }
    }
    
    func locationManager(_ manager: CLLocationManager, didFailWithError error: any Error) {
